CO2 Laser Skin Resurfacing in Ontario: What to Expect, Downtime, and Results

Skin changes gradually over time. Collagen production slows, years of sun exposure accumulate, and the skin’s natural repair processes become less efficient. These changes can lead to wrinkles, uneven texture, acne scars, and loss of firmness.

CO2 laser skin resurfacing is a widely used treatment for improving visible skin damage and signs of aging. By stimulating collagen renewal while resurfacing damaged skin, the treatment can improve both skin texture and overall skin quality.

At Derma Skin Institute in Guelph, we perform fractional CO2 laser resurfacing using the advanced eCO2™ laser system, a technology designed to deliver controlled skin rejuvenation while supporting natural healing.

Understanding how CO2 laser resurfacing works, what recovery involves, and how results develop can help patients determine whether the treatment is right for their skin.

What Is CO2 Laser Skin Resurfacing?

CO2 laser skin resurfacing is an advanced treatment designed to rejuvenate the skin by improving surface texture and stimulating new collagen production.

Modern fractional CO2 technology delivers energy to the skin in thousands of microscopic treatment zones. These tiny areas of controlled heat encourage the skin’s natural regenerative response while allowing surrounding tissue to support faster healing.

As the skin repairs itself following treatment, several changes occur:

• Collagen production increases
• Damaged skin cells are replaced with healthier new cells
• Skin texture becomes smoother and more even
• Wrinkles and fine lines soften
• Precancerous cells are removed, reducing risk of skin cancer
• Acne scars and sun damage improve
  

Because the treatment works both at the surface and deeper within the skin, CO2 laser resurfacing can improve multiple aspects of skin quality at the same time.

What Skin Concerns Can CO2 Laser Skin Resurfacing Improve?

For patients experiencing deeper wrinkles, acne scarring, or significant sun damage, fractional CO2 laser resurfacing can provide meaningful improvements in skin quality. Common concerns treated include:

• Fine lines and deeper wrinkles
• Acne scars and other textural irregularities
• Sun damage and uneven pigmentation
• Rough or uneven skin texture
• Enlarged pores
• Loss of skin firmness or elasticity
  

Because the treatment stimulates collagen remodeling while resurfacing damaged skin, it can improve both the appearance and structural quality of the skin.

What Happens During a CO2 Laser Skin Resurfacing Treatment?

CO2 laser resurfacing is performed in-clinic, with treatment plans customized to each patient’s skin and goals. At Derma Skin Institute, these procedures are performed by Dr. Sajic, a board-certified dermatologist in Canada and the United States. His background in medical and cosmetic dermatology, along with his understanding of laser technology and skin physiology, supports precise, individualized treatment planning and safe, effective outcomes.

Before the procedure begins, the skin is cleansed and topical and/or local anesthetic is typically applied to improve comfort. Our clinic provides options for pain and anxiety management.

Protective eyewear is placed over the patient’s eyes to shield them from the laser light.

During treatment, the eCO2™ fractional laser delivers controlled pulses of energy across the skin. These pulses create microscopic treatment zones that stimulate the skin’s natural healing process and collagen renewal.

Patients often describe the sensation as warmth or mild stinging during the procedure. Depending on the areas treated and the intensity of the resurfacing, treatments generally last between 30 minutes and one hour.

Once the procedure is completed, the skin is treated with soothing post-procedure topicals and protected with sunscreen to support healing. At Derma Skin Institute, this may include Sajic Skin Science Rejuvenat®, an advanced anti-aging peptide serum developed by Dr. Sajic, formulated to support the skin’s natural recovery process.

CO2 Laser Skin Resurfacing Downtime: What to Expect 

Recovery after CO2 laser resurfacing varies depending on treatment intensity, but most patients experience several days of visible healing as the skin begins to renew. All patients are provided with personalized post-treatment care instructions to optimize their results.

Day 1-3

Immediately following treatment, the skin typically appears red and may feel warm, similar to a sunburn. Swelling and sensitivity are also common during the early stages of healing. 

Days 3-7

As the skin begins its natural renewal process, patients may notice:

• Dryness and tightness
• Peeling or flaking as new skin forms
• Sandpaper-like texture
• Gradual improvement in skin texture as healing progresses

During this time, it is important to avoid picking or disrupting the skin, as this can affect healing. Patients are typically advised to keep the skin well hydrated, avoid sun exposure, and follow a gentle skincare routine as recommended by their provider.

For many patients, the most visible recovery occurs within five to seven days, though mild redness can persist longer as the skin continues to regenerate. Your provider will recommend a post-treatment skincare routine designed to support healing and protect the skin during this period.

When Will You See Results from CO2 Laser Resurfacing?

Some improvements in skin texture and brightness may be visible once the initial healing process is complete. The most significant changes occur gradually as collagen rebuilds beneath the skin, leading to improvements in:

• Skin firmness and elasticity
• Wrinkles and fine lines
• Texture and smoothness
• Overall skin tone and clarity
  

These changes typically continue to develop for three to six months following treatment as newly formed collagen strengthens and supports the skin.

Who Is a Good Candidate for CO2 Laser Skin Resurfacing?

CO2 laser resurfacing is often recommended for patients who want to address deeper wrinkles, acne scars, or more advanced signs of sun damage. Good candidates typically include individuals who:

• Have moderate to advanced textural concerns
• Are experiencing visible signs of aging
• Want more significant rejuvenation than lighter laser treatments typically provide
• Are comfortable with a defined recovery period
  

During consultation, your provider will assess your skin quality, medical history, and treatment goals to determine whether CO2 laser resurfacing is appropriate. In some cases, combination treatments may be recommended depending on your skin’s needs.

Why Treatment Planning Matters

At Derma Skin Institute, skin rejuvenation is approached as a long-term strategy rather than a single treatment.

While CO2 laser resurfacing can produce meaningful improvements in skin quality, the best outcomes occur when treatments are carefully selected based on each patient’s skin structure, degree of aging, and lifestyle considerations. Factors such as skin thickness, sun damage, collagen health, and recovery tolerance all influence treatment planning. 

For patients with early signs of aging or mild unevenness, less intensive modalities often deliver excellent results with less downtime. In many cases, comparable outcomes can be achieved through staged or combination approaches that better respect the skin’s biology.

By evaluating these factors, our providers can recommend treatment strategies that support both immediate improvements and long-term skin health.
